GROUNDING INSTRUCTIONS
This product must be grounded. In
the event of an electrical short circuit,
grounding reduces the risk of electric
shock by providing an escape wire
for the electric current. This product
is equipped with a cord having a
grounding wire with an appropriate
grounding plug. The plug must be
plugged into an outlet that is properly
installed and grounded in accordance
with all local codes and ordinances.
improper installation
of the grounding
plug is able to result in a risk of electric
shock. when repair or replacement of the
cord or plug is required, do not connect
the grounding wire to either flat blade
terminal. The wire with insulation having
an outer surface that is green with or
without yellow stripes is the grounding
wire.
Do not use adapter
with this product!
Never connect
green (or green and
yellow) wire to a live terminal.
Check with a qualified electrician
or serviceman when the grounding
instructions are not completely
understood, or when in doubt as
to whether the product is properly
grounded. Do not modify the plug
provided; if it does not fit the outlet,
have the proper outlet installed by a
qualified technician.
This product is for use on a nominal
120V circuit and has a grounding plug
similar to the plug illustrated in Figure
4. Only connect the product to an
outlet having the same configuration
as the plug. Do not use an adapter
with this product.
ExTENSION CORDS
To avoid loss of
power and
overheating, it is better to use
additional air hose instead of extension
cords to reach work area.
Use only a 3-wire extension cord that
has a 3-blade grounding plug, and
a 3-slot receptacle that accepts the
plug on the product. Make sure your
extension cord is not damaged. When
using an extension cord, be sure to use
one heavy enough to carry the current
your product draws. An undersized
cord results in a drop in line voltage
and loss of power and overheating.
[The table on page 3 shows the correct
size to use depending on cord length
and nameplate ampere rating. When
in doubt, use the next heavier gauge.
The smaller the gauge number, the
heavier the cord.]
Operation
• Pressure Switch
- ON/OFF Switch
(Figure 5) - In the ON position, the
compressor shuts off automatically
when tank pressure reaches the
maximum preset pressure. In the
OFF position, the compressor will
not operate. This switch should be in
the OFF position when connecting
or disconnecting the power cord
from the electrical outlet or when
changing air tools.
•
Regulator
- The regulator controls
the amount of air pressure released
at the hose outlet.
•
ASME Safety Valve
- This valve
automatically releases air if the
tank pressure exceeds the preset
maximum.
•
Exhaust Tube
- This tube carries
compressed air from the pump to
the check valve. This tube becomes
very hot during use. To avoid the
risk of severe burns, never touch
the exhaust tube.
•
Check Valve
- A one-way valve
that allows air to enter the tank, but
prevents air in the tank from flowing
back into the compressor pump.
•
Handle
- Designed to move the
compressor.
•
Drain Valve
- This valve is located on
the side of the tank. Use this valve to
drain moisture from the tank daily to
reduce the risk of corrosion.
Drain liquid from
tank daily.
Reduce tank pressure below 10 psi, then
drain moisture from tank daily to avoid
tank corrosion. Drain moisture from
tank by opening the drain valve located
underneath or on the side of the tank.
bEFORE FIRST START-UP
bREAK-IN PROCEDURE
(Complete this procedure before using
compressor for the first time. Once
completed, it is not necessary to repeat.)
1. Turn regulator knob fully clockwise
(to the right) to open air flow and
open drain valve.
2. Turn ON/OFF switch to OFF position.
3. Plug in power cord.
4. Turn ON/OFF switch to ON position
and run compressor for 30 minutes.

MOISTURE IN COMPRESSED AIR
Moisture in compressed air will form into droplets as it comes from an air
compressor pump. When humidity is high or when a compressor is in continuous use
for an extended period of time, this moisture will collect in the tank. When using a
paint spray or sandblast gun, this water will be carried from the tank through the
hose, and out of the gun as droplets mixed with the spray material.
IMPORTANT:
This condensation will cause water spots in a paint job, especially
when spraying other than water based paints. If sandblasting, it will cause the sand
to cake and clog the gun, rendering it ineffective. A filter in the air line, located as
near to the gun as possible, will help eliminate this moisture.
